SHEET-DELIVERY.

SPECIFICATION forming part of Letters Patent No. 719,317, dated January27, 1903.

Application filed August 13,1902- Serial No. 119,563. (No model.)

To ctZZ whom, it may concern:

Be it known that I, GEORGE P. FENNER, a citizen of the United States,residing at New London, in the county of New London and State ofConnecticut, have invented new and useful Improvements inSheet-Deliveries, of which the following is a specification.

By means of this invention the tape of a delivery mechanism can alwaysbe kept at a suitable degree of tension and accurate operation attained.

The invention resides in certain novel features of construction setforth in the following specification and claims and illustrated in theannexed drawings, in which Figure 1 is a side elevation of a deliveryembodying this invention. Fig. 2 is a plan View of Fig. 1. Fig. 3 is aside view of the tape-carriage, on a larger scale than Fig. 1, thecarriage moving backward. Fig. 4 is a view like Fig. 3, the carriagemoving forward. Fig. 5 shows a plan view of rolls for keeping the tapesstretched. Fig. 6 is a sectional view along 00 :0, Fig. 4, of atape-roll with clutch arrangement. Fig. 7 is a side elevation of aclutch-ring mounted somewhat differently from that shown in Fig. 6. Fig.3 shows a modification.

In the drawings are indicated an impressioncylinder 16 and tape-carriage17, which reciprocates and the tapes 18 of which are arranged so thattheir top side or stretch remains stationary or withoutmotion when thecarriage is moving back or toward the impression-cylinder. Thisarrangement of tape and carriage is known in the art and need not bedescribed here. (See, {for example, United States Patents No. 335,066,of January 26, 1886, and No. 506,990, of October 17, 1893. Sheetdelivery.) The tape rolls or wheels can for convenience of descriptionbe called rear roll 1, located toward the impressioncylinder, ant frontroll 2, with intermediate rolls 3 and a. Any one or more of these rollscould be selected as a tape-tightener roll; but a practical constructionhas been found to construct intermediate rolls-say 3as a tape-tighteneror combined with tightening mechanism. By selecting intermediate rolls,as 3 or 4, for tighteningitis possible to get all of the action of theseti ghtener-wheels without its being necessary to increase the length ofthe run of the delivery-carriage. In the drawings the roll 3-that is,theseries of disks which limits the movement of the wheels 3, so that ifthe tape should become excessively slack the wheels 3 cannot extend ormove to such an extent as to strike against roll 1. The advantage ofsuch tightening arrangement is manifest from the above explanation. Suchtighteners, among other things, will take care of increased anddecreased length of tape because of atmospheric changes.

In the operation of the machine as roller 3 moves back and forth withthe carriage and one part or another of the tape tends to slacken thetightener-sprin gs coming into action will keep the tension of the tapeuniform. Say, for example, on the roll 3 moving away from roll 4 thetape should slack, the spring will preserve the tension of the tape, orwhen roll 3 starts its backward motion toward roll 1 and the tape shouldbe shortened, the spring is compressed, and roll 3 moves somewhat moreslowly than the delivery-carriage until the tape has resumed its normalposition. Manifestly, the same ac tion is produced when thetightener-wheels are in the position of roll 4, Fig. 8. The roll 3 inthat case could be the ordinary roll as heretofore used. It may be notedthat if the roll l should come under the position of roll 3 it would benecessary to drop the sheet correspondingly farther ahead on thedeliveryboard; otherwise the back edge of the sheet might strike theroll 4. In case the inking apparatus is located under the delivery-boardthe farther front the sheet is delivered the more will access to theink-rolls and inkfountain be interfered with. The selection of roll 3for the tightening action mentioned is considered the most practical;but of course no limitation of the invention is thereby intended.

The tape-carriage is shown running on a track, which latter for acertain part of its length is hinged or movably mounted. Such track ormovable section 9 can thus be swung out of the way to allow ready orfree access to the front of the cylinder. The movable track part orrails 9 can be balanced by suitable means, such as a rope running over apulley and attached to a weight 10. By this arrangement the type as wellas the cylinder are easy of access when the delivery is out of the way.

In using ratchet-wheels and dogs to prevent the delivery-rolls fromturning backward it has been found that variations in delivering thesheet occur. The dogs do not always drop into the teeth in perfectregister with the preceding sheet. In other words, the sheet does notcome to a standstill every time in just the same place, because thetapes are not exactly controlled by the ratchetwheels and dogs. The dogsand ratchetwheels are also undesirable because of the noise theyproduce. Objections of this nature are avoided by substitutingfrictionclutches, as shown, for example, in connection with rolls 1, 2,and 4. These clutches work with accuracy, allowing no backlash to thetape. These clutches can be arranged as follows, taking, for example,roll 1: To said roll or the shaft thereof is attached a disk 11, Figs.4, 5, and 6, with cam-surfaces for the action of rolls 12, each exposedto the action of a spring tending to hold the rolls in constant contactwith the cam-surface of disk 11 and wit-h the internal surface of a ring14, inside of which the rolls 12 work. Roll 1 is thusallowed to revolvefreely in one direction, as indicated by the arrow at the same, Fig. 4;but as soon as reverse action starts then the disk 11, with itscam-surfaces, impinges the rolls 12 against the inner surface of ring14and instantlystops or prevents such reverse action. Ring 14, it hasbeen found, should be free to conform or adjust itself to irregularitiesthat may exist, say, in the bearings of roll 1 or to follow the positionof roll 1 as its bearings wear from use. As roll 1 is worn on itsjournal it moves to one side. This throws the clutch out of center andpreven ts its perfect action. These irregularities may be but slight;but it is thought advisable they be provided for, which can be done byhaving ring 14 free to conform thereto. These disadvantages can beovercome, as shown, by having a slip connection between ring 14 and thecasting forming part of the bearing for roll 1. A pin-and-slotconnection are shown. The pin is shown at 15, and the slotted hole ofthis connection is made to accurately fit this pin, which goes throughor is carried by the bearing-casting. The ring 14 is thus effectuallyprevented from rotating in either direction, but is allowed to followroll 1 in its movement from wear or other cause.

A modified form of connection is shown in Fig. 7, a link connectionbeing shown at 15 connecting the ring with the support or solid casting.Like rings 14 and clutch arrangements are shown at rollers 1, 2, and 4or at roll 3 in a modification such as shown in Fig. 8; but thedescription of one clutch serves to explain the others.

What I claim as new, and desire to secure by Letters Patent, is

1. A delivery apparatus comprisinga reciprocating tape-carriage and atrack therefor .having a hinged section, rear and intermediatetape-rollers supported by the track, and front and intermediatetape-rollers carried back and forth by the carriage, one of said rollersbeing composed of independentlymounted spring-pressed disks one for eachtape to maintain each respective tape in proper tension.

2. A'deliveryapparatus comprisingareciprocating tape-carriage and atrack therefor, rear and intermediate tape-rollers supported by thetrack, and front and intermediate taperollers suspended from and carriedback and forth by the carriage, said intermediate rollers suspended fromthe carriage composed of independently-mounted spring-pressed disks onefor each tape to maintain each respective tape in proper tension.

3. A delivery apparatus comprisinga reciprocating tape-carriage and atrack therefor having a hinged section, rear and intermediatetape-rollers supported by the track, and front and intermediatetape-rollers suspended from and carried back and forth by the carriage,the intermediate roller on the carriage being composed ofindependently-mounted springpressed disks one for each tape to maintaineach respective tape in proper tenslon.

4. A delivery apparatus comprising a reciprocating tape-carriage and atrack therefor, rear and intermediate tape-rollers supported by thetrack, and front and intermediate taperollers carried back and forth bythe carriage, one of said rollers being composed ofindependently-mounted spring-pressed disks one for each tape to maintaineach respective tape in proper tension, and the rear roller beingprovided with a clutch to prevent reverse rotation thereof and compelthe tape to travel about the rollers in one direction only.

5. Adelivery apparatus comprising a tape carriage and rolls, and aclutch comprising a ring movable or adjustably mounted to be set tocorrespond to the position of its roll.

6. A delivery apparatus comprising a tape carriage and rolls, and aclutch comprising a ring and a slot-and-pin support for movablysupporting the ring.

7. A delivery apparatus comprising delivery-tapes and rolls and a clutchfor preventing reverse action of the rolls, said clutch comprising aring having 'a movable connection or support to prevent the ring fromre-- volving while allowing the same to move or be adjusted.

In testimony whereof I have hereuntoset my hand in the presence of twosubscribing witnesses.
